About This Manual
This document is organized into sections that correspond to each major feature; it explains the features
and functionality of each module, and it also explains how to use them. For each feature, references are
given to the documentation for the driver of the corresponding operating systems. This document does not
contain performance characteristics of the device or modules, which are gathered in the corresponding
device data sheets.
Register Bit Conventions
Table 0-1 lists each register with a key indicating the accessibility of the individual bit, and the initial
condition.
